Southern Outlet transit lane

We are timing these works to minimise traffic impacts and make sure we aren’t working on too many sections at the same time.

We have done investigations of the rockface at the southern end of the proposed Transit Lane site.

The rockface is safe, but needs further protection works to be completed before we start on major the construction of the Transit Lane, to reduce the risk of rocks falling during construction.

The rock protection work will start just down from the Olinda Grove ramp, for a distance of about 400 metres.

This work is expected to start in mid-2024 and take about 12 months to complete.

Why is this work being done?

After extensive site investigations, particularly of the rockface near the Olinda Grove ramp, our engineers identified a risk of rockfall during the construction of the Transit Lane. While there is no current risk to road users, they found that the vibration and rock breaking work associated with construction could result in rockfall. This means further rock stability and protection works were required before major construction work began.

Is there a current threat to road users?

No. The identified risk is related to the potential impact of significant construction work in the area.

What impact will the works have on traffic?

This is still to be determined and will be discussed with the successful contractors from the tender process. The priority is the safety of road users and workers involved in the project. Other considerations will be the timing of the works, including the suitability of night works, and noise issues.

How much of the rockface will need to be protected?

At this stage, we are looking at rock protection work for an area around 400 metres long.

When will work start and how long will it take?

The tender is expected to be awarded in 2024  with work expected to start on the rockface protection in mid-2024 and take around a year to complete, weather permitting.
